Uhll'lEQ d'lA'l'ES HARRY F. BLOOM,

VACUUM To all whom it may concern Be it known that I, HARRY F. BLooM, a citizen of the United States, residing at Toledo, in the county of Lucas and State of )hio, have invented a new and useful Vacuum Oil-Cup, of which the following is a specification.

This invention relates to vacuum oil cups and is designed more especially as an improvement upon the structure disclosed in Patent No. 1,835,477 issued to me on March 30,1920.

One of the objects of the invention is to provide a structure of this character in which the filling process can be carried oil without removing the cover or disturbing the adjusting screw, it being possible to lock the adjusting screw in place after it has been regulated to allow the escape of the desired amount of lubricant, the cover of the cup being easily removable without disturbing the nut.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is an elevation of the oil cup constituting the present invention.

Fig. 2 is an enlarged section therethrough.

Fig. 3 is a section on line 33, Fig. 2.

Fig. 4 is a section on line 44, Fig. 2.

Referring to the fi ures by characters of reference 1 designates the neck of the device preferably formed with an angular portion 2 adapted to be engaged by a wrench and extending at one end of this neck is an eX- teriorly threaded nipple 8 while the other end of the neck is formed with an annular shoulder 41: surrounding a threaded boss 5. A tubular stem 6 projects from this boss and is surrounded, close to the boss, by an annular shoulder 7 forming a gutter 8.

Formed upon the stem 6 is an annular shoulder .9 overhung by a conical shoulder 10 extending around the stem and outwardly beyond the edge of the shoulder 9. Ports 11 extend inwardly from the shoulder 9 to Specification of Application filed April 21,

the bore within the sleeve-and additional ports 12 extend fromthe gutter 8 into the bore in the boss 5.

That end of the stem 6 remote from the body 1 is threaded exteriorly as shown at 13.

Adjustably mounted in the stem 6 is a ieedle valve 1 1 the pointed end of which is adapted to be adjusted relative to a tapered seat 15 formed within the body 1. That portion of the stem 6 between the ports 11 and 12 is interiorly screw threaded, as at 16, for engagement by threads 17 formed upon the needle valve 14 and which threads are intersected by longitudinal grooves 18. The on er end portion of the needle valve is also screw threaded, as shown at19 and has a kerf 20 in the end thereof. This threaded end portion 19 is adapted to be engaged by a lock nut 21 designed to bear against the end of the stem 6.

A globe-like body 22 is screwed onto the boss 5 and bears against the shoulder 4 so that the outer surface of this body is flush with. the outer surface of the neck 1. The other end of the body has a depression 23 concentric with the stem 6 and having slots 24: therein opening into the interior of the body. The walls of this depression are tapered and form a seat for a cover 25 in'the form of a nut which engages the threaded portion 13 of the stem and which is adapted to prevent the escape of lubricant through the slots 24.

It will be understood that, without disturbing the cover 25, the needle valve 14: can be adjusted. simply by loosening the lock nut 21 and rotating the valve 14- by means of a screw driver or the like inserted into the kerf 20. Likewise the body 1 can be filled without disturbing the adjustment of the needle valve, simply by unscrewing the cover 25 so that it will become disengaged from the seat formed by the wall of the depression 23 and will ride upwardly onto the lower reduced portion of the nut 21. Lubricant will pass through the ports 12 or 11 or both into the bore in the sleeve 6 and will, flow along the grooves 8 and be delivered through the nipple 3 to the rotating element to be lubricated, the amount of lubricant discharged being regulated by the adjustment of the valve 14.

It is to be understood that the peripheries of the cover 25 and the nut 21 can be milled as shown in Fig. 1 to facilitate the rotation thereof by hand.

What is claimed is:

1. In a vacuum oil cup a neck having a valve seat therein, an outlet opening, a body mounted on the neck, a tubular stem integral with the neck and within the body, said stem having ports therein for establishing com munication between the interior of the body and the interior of the stem, a valve adjustably mounted in the stem and adapted to engage the seat, one end of the valve projecting beyond the body, a cover for the body and detachably and adjustably engaging the stem, said cover being shiftable to open position without becoming detached from the oil cup or disturbing the adjustment of the valve.

2. In a vacuum oil cup a neck having a valve seat therein and an outlet nipple, a tubular stem projecting from the neck and having an annular shoulder, there being portsextending from the shoulder and into the stem, a valve adjustably mounted in the stem and adapted to engage the seat, one end of the valve projecting beyond the stem and body, a lock nut engaging said valve and adjustable against the stem, and a cover adj ustably engaging the stem and movable toward and away from the body to close and open said body, said lock nut constituting means for holding the cover against removal from the cup. 7

3. In a vacuum oil cup a neck having a valve seat therein and an outlet nipple, a tubular stem integral with and extending from the neck, said sleeve having an annular shoulder and ports extending from the shoulder and into the bore in the sleeve, a needle valve adjustably engaging the sleeve and projecting beyond one end thereof, a body engaging the neck and housing a portion of the sleeve, said body having an inlet slot in one end, there being a depression within said end of the body forming a seat,

a closure adjustably engaging the stem and adapted to bear upon the seat to close the slots, and means engaging the needle valve and bearing against the sleeve for locking the valve against rotation and for limiting the movement of the closure when ruis e a'ted.

In testimony that I claim the foregoing as my own, I have hereto aifixed'my' signature
